.construction and combination of a grooved and ribbed drum whichrevolves with the axle and adjustable feed-regulating slides which coactwith the drum, as hereinafter described.

In the accompanying drawings, Figure 1 is a sectional elevation of themachine, the section being on line 1 1 of Fig. 3. Fig. 2 is across-section on the line 2 2 of Fig. 1.. Fig. 3 is a plan view of themachine, omitting the hopper; and Fig. 4is a longitudinal section on theline 4 4 of Fig. 3.,

The machine-frame A is provided with handles a and mounted upon anaxleB, to which running-Wheels C' are keyed (see Figs. 1 and 3) so thatthey revolve together: Upon said axle is'mounted a ,drum or roller D,which is keyed thereto so as to revolve with it. This drumis providedwith a series of circumferential ribs (1 and grooves d, which alternate,as shown inFigs. 2 and 3. The drum is arranged in such manner that itsupper portion or segment projects into the bottom of the hopper E. (SeeFig. 4.) Within the hopper I propose in practice to arrange a suitableagitator, such as is commonly employed in fertilizer-distributers ofthis class. The hopper E is secured upon and to a rectangular frame F,(see especially .Fig. 3,) which is in turn securedupon transverse barsor beams G, that extend between and connect the middleportions of theside The means for regulating the dischar e of the fertilizer is aseries of slides H, w 'ch'are in the nature of narrow slats or thin barshaving parallel sides and arranged close to ether, ,as shown in Fig. 3.The outer'ends '0 these regulators rest upon a transverse bar I and arepro- -vided with lengthwise slots 7 to receive clamping-bolts h. Theinner ends of the feed regulators or bars H pass through slots M oropenings formed between the frame F and the underlying bars G, as willbe understood by reference to Figs. 2 and 4. Thus the feed regulatorsare supported firmly in their required position, but adapted for speedyadjustment with relation to the drum Dthat is to say, they may beadjusted lengthwise in order to increase or lessen the distance betweentheir inner ends and the opposite portions of the drum for the purposeof allowing the eater or less discharge of fertilizer, as con itions mayrequire. It will be noted that the slats H correspond in number with theaggregate number. of the ribs d and grooves d of the drum andthat theirwidth is the same as the said ribs and grooves. Thus each slat isarranged opposite a rib or groove, those which are opposite the groovesbeing adapted'to project more or less into the latter, as shown in Fig.4. As the machine is drawn along the friction of the runningwheels Owith the round serves to revolve the drum or roller in the direction ofthe arrow, Fig. 4, and thereby the fertilizer is carried down byfriction with'the drum and discharged broadcast, providing all the slatsor feed-regulators H be adjusted at a distance from the periphery of thedrum. It is obvious that if those slats which are opposite.

discharged in streamsthat' is to say, from the ooves alone; Ordinarily,however, the several slats H will be so adjusted as to allow dischargefrom the" entire surface of the drum.

It has been found that by means of a drum providedwithribs and grooves,as shown in the drawings, fertilizer can be distributed withgreateruniformity and'regularity than with a drum having a smoothperiphery, since lumps or compact portions of fertilizer which are toolarge to pass through the spaces between the drum and the adjacent endsof the slats H cannot obstruct the feed of fertilizer through thegrooves to the same extent that they would do if lying in contact with adrum having a smooth periphery. Further, the lumps are subjected to arubbing or a frictional action with the edges or sides up much fasterthan is possible with a drum having a smooth periphery.

" For the purpose of removing from the gular drum-that is to say, bothfrom its ribs and grooves-a11y' portion of fertilizer which may adherein the feeding operation I provide a second series of slats H, the samebeing arranged in the rear of the drum in ractically the same manner asthe feed-regu ating slats H. It will be understood that. theseslats Hare always adjusted close to the periphery of the drum, so as to act asscrapersfor the latter.

My improved fertilizer-distributer is simple and inexpensive inconstruction, while of: fective in operation, and an adjustment ofdevices for regulating the feed may be easily and uickly made. z 1

What I claim-is- 1'. Theimprovedfertilizerrdistributer,corn? a mainframe, an axle upon which lt'lS mounted, runningfwheels which aresecured to the axle, a drum fixed on the axle so as to revolve with itand'provided with a series ofalternatingperipheral ribs and grooves, ahopper arrang over the afrectaname sicurfd upon the mam Iframe and supor t 'e opper, a space eing provided between said frame andtheunderlying portion of. the main frame and a series of ad- I us tablebars or slats constituting feed-regulators, the; same. being supportedhorizon..-

their inner ends proecting through the space in the frame and into dueproxlmity to the siu'f-ace of thedrum,

the said. slats having thesame number and praatically the, same. widthas the ribs and v grooves of the drum,. substantially as dei scribed.

2. Theimprovedfertilizer-distributer,com

a .mam frame, an axle whereon the prising same is mounted,running-wheels secured tothe axle, a drum mounted fast" on the axle,thus revolving with it, the same being provided with alternating ribsand grooves, a

hopper located above the drum, means for regulatingvthe feed ordischarge of the fertilize'r, and scrapers located in the rear of thedrum and comprisin a series of bars or slats lying side by side, tcontact with the perip ery of the drum and their. outer ends ,securedad'ustably to the frame, substantially as described.

3.
